With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78364-55-3,6-Fluoro-2-hydrazinylbenzo[d]thiazole,as a common compound, the synthetic route is as follows.
General procedure: A mixture of 2-hydrazinobenzothiazole 1a (0.825 g, 5 mmol)and alpha-cyanoacetophenone 2a (0.73 g, 5 mmol) was refluxed in ethanol containing acetic acid (3ml) for 5-6 h. Excess solvent was removed by distillation. The crude product so obtained was recrystallized from ethanol to give 5a (1.09 g, 75percent), Mp 201 ¡ã C (lit.[20], 202 ¡ã C). Other compounds (5b-d) of this type were prepared similarly.
78364-55-3, The synthetic route of 78364-55-3 has been constantly updated, and we look forward to future research findings.
